Instruction Descriptions
ADDLW
Add Literal and W
Syntax:
[
label ] ADDLW
k
Operands:
0
≤ k ≤ 255
Operation:
(W) + k
→ (W)
Status Affected:
C, DC, Z
Encoding:
11
111x
kkkk
Description:
The contents of the W register are
added to the eight bit literal ’k’ and
the result is placed in the W regis-
ter.
Words:

ADDWF
Add W and f
Syntax:
[
label ] ADDWF
f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
